Annual nearly millions of the hard disks of China need to be eliminated because the reason such as damaging, too outmoded, more USB flash disk needs to destroy, so huge destruction scale, if can not coordinate effective ladder of management and technological means, certainly will cause the unthinkable consequence of divulging a secret.
Data destroying technology at the beginning of being born in 21 century is the formation sign of confidential data information security field integral framework, if " data recovery technique " likened to " lance " of confidential data information security field, " data destroying technology " is exactly " shield " of confidential data information security field so, and the effect of " shield " is better than " lance ".
Present stage common data destroying mode be that data override, demagnetization, disk body destroy three kinds of modes and separately carry out, and destroys thoroughly not, and destruction speed is slower.
Data erase is before unclassified data are write, to have the process of the memory location of sensitive data.Data on hard disk are all with binary " 1 " and the storage of " 0 " form.Use predefined meaningless, irregular information to cover the data of original storage on hard disk, after overriding completely, just cannot know that original data are 0 or 1, have also just reached the object clearing data.Adopt dissimilar data, the method that the memory location of the data that delete is repeatedly override, is the effective way of data destroying, and the hard disk after processing can recycle.
Demagnetization operation realizes by degausser conventionally, and the principle of work of degausser is that magnetic-based storage media (as hard disk, tape) is applied to moment high-intensity magnetic field, and the magnetic-particle polar orientation of dielectric surface is changed, and loses the meaning that represents data.The most outstanding feature of demagnetization is exactly quickness and high efficiency, facilitates monitoring and auditing, can operate in Office Area.Hard disk after demagnetization can not directly use, and can be used for after service or abandons.
Hardware destroy adopts the method for physical damage or chemical corrosion that the physical support that records confidential data is destroyed completely conventionally, thereby fundamentally solves the problem that data are revealed.
In above three kinds of methods, only have the hard disk after data erase just can recycle, so data erase has also become the technology of most economical practicality in data destroying technology.
The problems such as existing domestic and international data erase technology ubiquity function singleness, erasing speed is not high, concurrent operations number is few, operating result cannot be determined.
